Jerry:
Is the HP 1745 a good'un then? I have had a 1745, with two TEK P6131 10X
passive probes for a few years, but was unable to find a manual for
it when first
bought it, and have not tried for a while now. Never used a scope enough to
even know HOW to use one, but enjoy reading postings from you particularly,
along with a few of the other guys that seem to know what they are
talking about.
I have been a big fan of Ten Tec for a lotta years, and have a stable
of 7 of their
rigs dating from the Omni VI Option 3, back thru the Triton IV
digital. I am also a
big fan of Elecraft, and built the K2 #317 and K3 # 833.
Appreciate your opinion on the 1745.
Thanks, 73 Dub K5DUB
